Technical Specifications
The Brightline West system is designed for high efficiency and safety, with its alignment primarily located within the median of the I-15 highway. This design strategy eliminates all at-grade crossings, a critical safety feature for a line operating at speeds exceeding 200 mph. The infrastructure includes over 160 structures such as viaducts and bridges, extensive retaining walls for grade separation, and a sophisticated overhead catenary system for consistent electric power delivery. The primary rolling stock consists of Siemens’ American Pioneer 220 (AP 220) trainsets. These all-electric units are engineered for operational efficiency with a lightweight, wide-body, and aerodynamic profile. They are fully compliant with Americans with Disabilities Act (ADA) and Rail Vehicles Access Advisory Committee (RVAAC) guidelines, ensuring broad accessibility. A primary Vehicle Maintenance Facility (VMF) in Sloan, Nevada will serve as the central hub for operations, maintenance, and control.
Key Takeaways
- Economic Catalyst: The project is a major economic driver, projected to create over 35,000 construction jobs and 1,000 permanent positions, while injecting billions into the regional economy through tourism and commerce by serving an estimated 11 million annual passengers.
- Environmental Sustainability: As a fully-electric, zero-emission system, Brightline West will significantly reduce regional carbon footprints by eliminating an estimated 400,000 tonnes of CO2 annually and removing millions of car journeys from the congested I-15 corridor.
- Infrastructure Modernization: The project serves as a crucial proof-of-concept for modern high-speed rail in the United States, showcasing a successful public-private partnership model and setting a new standard for intercity passenger transport.
